Part 29

In the initial area, kill the six enemies, grab the armour and ammo, and proceed to the first checkpoint (an auto-save point you restart from on death).

Continue upwards, freezing masos and using your shotgun on other enemies. Grab health and ammo. You can push a barrel through the door to set a trap. Conserve rockets for later.

Head right towards a small radar (your minimap with nearby blips and threats marked) hut, pushing a barrel ahead. Shoot the barrel when soldiers and masos appear to eliminate the first wave. Use your chaingun to finish them off. Going around the main building triggers another wave; use rockets for these enemies, but avoid shooting the three barrels against the wall.

SECRET 1: Collect ammo from the guardpost, bunker, and two huts. Quick-jump up three barrels to reach a holy item in a secret area.

Shoot the flaming barrel through the fence to make a truck roll down a ramp and break the gates. Go through the opened gates. If the lower gates don't break, jump onto the truck and over. More sados will spawn uphill; shotgun them and pick up armour from the hut above the truck. Proceed to the next checkpoint in the other hut.

As the doors close, a sado will appear behind you; kill it. Poke your head out and deal with more commandos. Collect enough souls for a Morph (try to miss at least one, as it's not ideal here) and let the door into the building open.

Clear the room, using your Morph if available. Collect ammo and gold from boxes. Step onto the lift to go down. Prepare your freezer for a maso commando in the hallway, then hit the checkpoint.

Use your chaingun to clear the room and the long corridor. Grab ammo behind computers, then eliminate enemies at the other end of the corridor.

SECRET 2: Drop to the bottom of the missile chamber and grab the holy item in the secret area.

Climb the ladder and use your freeze and shotgun to deal with commandos entering the shaft. Climb the next ladder on the inner wall for more masos, then the next ladder on the inner wall of this floor for more commandos at the top. Grab armour, return to the missile chamber for ammo, and reach the checkpoint.

This is the toughest part. Upon exiting the ladder, you will be attacked by nearby mortar guns and three tanks. Each tank requires five or six rockets to destroy and counts as one kill. Soldiers will also attack; dodge or seek cover (press the cover button to crouch behind walls or objects) in the doorway to your left.

You should be near a Morph. Clear the tank, three mortars, and soldiers on this side of the plane, then enter the plane for health. More soldiers will spawn inside; run out the front and lure them towards the garages. Two more tanks and more soldiers will appear as you approach. Kill one or two soldiers to trigger your Morph, then easily clear the area, prioritizing the tanks.

SECRETS 3 & 4: Some garages contain ammo boxes. The secret area in the plane is reached by pushing a box under the half-ladder, then jumping up and forward for ammo, super-health, and heavy armour. Another secret area is on top of the plane, accessible by quick-jumping onto the wheel and up the side for mega ammo packs.

Explore each of the three bunkhouses next to the garages from the back. Wait for the door into the sleeping area to open, revealing monsters. Ensure all three bunkhouses are explored to meet the kill ratio requirement. The plane and bunkhouses are essential areas for killing all monsters; the directional arrow (waypoint (a marker on your map you've manually placed as a destination)) may become unreliable here.

After exploring the bunkhouses, climb the last ladder and hit the exit.
